[edit] I did some experimenting, it seems that the local menu is displayed when you release the "VKMENU key" so my guess is that you catch the keydown event, bring up the edit field, set the focus to it, and then when the key is released then the keyup events goes to your edit box and tadaa, it displays the menu. Maybe try displaying your box on keyup instead of keydown if that workds for you.
